<p>&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;valid_referers none blocked server_name 表示对这些域名的网站不进行盗链。</p>
<p>&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;然后 if ，可以 deny all 也可以 return 403，然后 rewrite 到一个403的固定网页。这样盗链文件的人访问这些文件时就会跳到 <a href="http://www.example.com/nophoto.gif" target="_blank" rel="external">http://www.example.com/nophoto.gif</a> 这里。当然也可以直接显示 403，即 return 403; 着两种方式 return 403 更节省资源。</p>
